Is There a Change in Ally and Dan?

Journalists have been following two scientists for three years. Have you seen a change in them as they've followed their research? Do you think they've changed? Why? We didn't provide any coaching along the way, at least i don't think we did. I think ally has become more confident about presenting her science and explaining sort of concisely what it is that she's doing. For dan it was a matter of explaining things in a way that a non specialist could understand.
